It was a blast to have Tanya Lerch on the show. This incredibly smart and energetic runner, teacher, mother, and founder of a pediatric non-profit brought the goods in this episode.   We touched on so many things, not the least of which was her transition from a 4:38 to 3:08 marathon. We also talk about an amazing project that her and her students are engaged in that provides prosthetics to children whose families can't afford such devices. Learn more about that here: https://www.sageprosthetics.org/ Not only that, in 1988 she participated in a follow-up study to the hallowed Stanford marshmallow experiment. This experiment was a study on delayed gratification in 1972 led by psychologist Walter Mischel, a professor at Stanford University. In this study, a child was offered a choice between one small but immediate reward, or two small rewards if they waited for a period of time. During this time, the researcher left the room for about 15 minutes and then returned. In follow-up studies, the researchers found that children who were able to wait longer for the preferred rewards tended to have better life outcomes in many areas. It was a controversial study that we had a lot of fun discussing. Sponsors: Previnex is a supplement brand that I trust, use, and have greatly benefited from.
